The man accused of killing a Louisville Metro Police detective after crashing into her parked police cruiser on Christmas Eve had a narcotic in his system, a Jefferson Commonwealth's Attorney spokesman confirmed Friday.

A toxicology report, which has not been publicly released, indicated that Roger Burdette had hydrocodone in his system, spokesman Jeff Cooke said.

Burdette admitted to taking multiple prescription drugs, according to an arrest citation from December, and police said he showed multiple indicators of impairment during a field sobriety test.

Police also previously testified that Burdette told officers after the crash that he takes medications for blood pressure and cholesterol, as well as Zoloft — which can be used to treat depression, obsessive-compulsive disorder and anxiety — and an antibiotic that could cause dizziness.

Police say on the afternoon of Dec. 24, Burdette struck Detective Deidre "Dee Dee" Mengedoht's police vehicle from behind as she conducted a traffic stop on Interstate 64 East underneath the Belvedere.

Burdette was a Metropolitan Sewer District employee at the time of the crash and was driving an MSD tractor-trailer. He has since been fired from the agency.

The 60-year-old faces charges of murder, driving under the influence, four counts of wanton endangerment and failing to give the right of the way to a stopped emergency vehicle. He was originally charged with murder and DUI in December and pleaded not guilty.

Burdette appeared in court Friday for a bond hearing, where a prosecutor told a judge that Burdette was on oxycodone and clonazepam, an anti-anxiety drug, while on duty, according to media reports. The prosecutor's office later clarified that was a misstatement, and that it was hydrocodone, not oxycodone.
